v1.4.0 May 26, 2020
ADDED
- **2.6.2.d **Plugins must introduce new editor functionality, integrate UE4 with third party systems, or expose complex gameplay logic to blueprints. Although extra scripts and assets may be distributed with a plugin to be used in supplementary tools (such as 3D modeling software, database management systems etc.), the majority of the submission must provide additions or modifications to be used in the Unreal Editor directly.
- 2.6.2.e Plugins must not distribute .exe or .msi files.
CHANGED
- **2.6.2.a Code plugins must not be ‘closed-source’ with regard to any source code the publisher created **which requires Unreal Engine source code to compile; that code must be included in the zipped up plugin folder. The only externally compiled code (static libraries or DLLs) that would be acceptable for including in a submission would be code which does not include or reference any Unreal Engine source code. Customers should have the plugin source code that’s dependent on Unreal Engine source code so that they may attempt to compile it against source-built versions of the engine.
- **2.6.2.c **Plugins must contain at least one module of C++ code but can contain content as well.
- **2.7.3.c **Starting with the overarching plugin folder (the one containing the Source folder and .uplugin file), all file paths must be 170 characters or less.
